I’ve used GQRX for the last year controlling GQRX quite successfully, and recently obtained a 706MKIIG. I cannot for the life of me get the rig control to work. rigctl is installed, and I can run it an manually change and query frequency - but that’s it. No luck with having gpredict control it. I start rigctr with:
rigctl -m 311 -r /dev/ttyUSB0
And then start gpredict. The radio is configured as localhost with 4532 port. Not sure how to check if gpredict is actually sending commands or not, but if I keep the terminal window that is running rigctl on top, I see nothing being sent to that terminal.
Alex, sorry for the late response. Haven’t tried it yet (in detail), as my 706 appears to be unhappy with the SWR of my arrow antenna. Keying up at even the lowest power setting forces the transceiver to shut down. I hope to try again soon.
